Reaction Steps

Analogously to the procedure of Example 63, 54 mg (146 μmol) of [3-(5-chloro-2-thienyl)-4-(2-fluorobenzyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetic acid [for the preparation see Example 154A in WO 2007/134862] were reacted with 49 mg (161 μmol) of tert-butyl {2-amino-1-[2-(trifluoromethyl)phenyl]ethyl}carbamate. This gave 64 mg (67% of theory) of the title compound.
